Brad Bird‘s new film, written byDamon Lindelof and Bird, and developed at Disney, has been going under the working title 1952 for the past few months. That led to plenty of speculation about the nature of the story, but Bird and Lindelof have been tight-lipped rather than reveal any details. The biggest teaser we’ve had was a recent photo of a box of archive materials that the two revealed last week.

Now the biggest tease is out: the working title 1952 has been scrapped, and the real title, Tomorrowland, announced in its place. Combined with elements revealed from that box, such as photos of Walt Disney, the title must be assumed as a reference to the Tomorrowland attraction opened at Disneyland in 1955.

EW reports the title change, but doesn’t have any further info. (The article notes that EW’s own Jeff Jensen is part of the script development, but that he has given the outlet nothing it can run on the story.)

So what do we know about the film? What we think we know is this: despite the working title, it is set in the present day, and starsGeorge Clooney in a story about aliens making contact with Earth. The box revealed last week was “a banker’s box of files and documents that had been left moldering in Walt Disney’s personal development lab,” which was labeled 1952. One of the items in the box is a 1928 issue of Amazing Stories featuring a character that eventually became Buck Rogers.

None of those little details may really play a part in what Tomorrowland actually is. It’s a good puzzle at this point, and the title reveal is sure to fuel significant new speculation about the trajectory of the script, and how it really relates to Walt Disney’s early attempt at visualizing the future.

Update: After the title was announced today, Damon Lindelof attempted to correct some info floating around about the film:
